Description

A juicer and a juicer method comprising the same

The present invention relates to a juicer and a juice extraction method comprising the same, and more particularly, to a juicer with improved juice performance and a juice extraction method including the same.

In general, a juicer is a kind of green juicer that extracts juice by squeezing various vegetables or fruits, and mainly uses a centrifugal separation method and a twin gear method.

The centrifugal separation method is suitable as a juicer for extracting fruit juice, such as fruits, but vegetables with high fiber content and low moisture content are minced for juice extraction and the juice extraction rate is not very high even if they are rotated at a fairly high speed, and residual heavy metals are discharged There were problems such as

In contrast, the twin-gear method extracts juice by slicing and squeezing the material or simultaneously slicing and compressing the material. The juice extraction rate is several times higher than that of the centrifugal separation method, and there is an advantage in that residual heavy metals are not eluted together in the green juice. Most of the market demand is for this twin-gear type juicer.

Such a twin-gear juicer is provided with a pair of crushing units in the form of helical gears and a pair of conveying units in the form of Archimedes spirals, and after accommodating the crushing unit and conveying units in a housing in which the juicer network is formed, It is made by coupling the housing and the driving part through a fastening part.

The pair of crushing units are driven by the driving unit and rotate while interlocking, crushing and pulverizing the input material and transferring it to the conveying unit while juicing, and by pressing while conveying the crushed material in the conveying unit, juice can be extracted from the material. .

However, the conventional juicer has a problem in that the juice rate is significantly reduced as it is provided to press with the same driving force for all materials by the above-described driving unit and conveying unit regardless of the type of material to be juiced.
